Emperor
From Encyclopædia
Emperor is a title given to certain sovereign heads of state, especially those controlling vast and disparate territories. The title is derived from the Latin imperator; it was first used to refer to the ruler of ancient Rome. The title was revived in Western
Europe by CHARLEMAGNE in the 9th century and used by the rulers of the HOLY ROMAN EMPIRE. It was adopted by the tsars of
Russia (1721) and, in the 19th century, by NAPOLEON I and NAPOLEON III of France, the HOHENZOLLERN rulers of Germany, and by several rulers in Latin
America. The British monarch was called empress or emperor of India from 1877 to 1947. Emperor has also been used to refer to some non-European sovereigns whose titles have no Western equivalent, like the traditional rulers of China and Japan.
